• The orange disc is the opened OTA door

• The blue cube is the spacecraft bus

• The yellow sections are radiators

Please note that the colours shown are not representative of the real spacecraft. They are for display purposes only. You may like to compare Figure 1 with the spacecraft drawing on the Solar-B introduction page, though please note that this was created in the beginning of the Solar-B mission design phase, while the thermal model represents the latest Solar-B design.
